PREFACE
So much has been written popularly and in a scientifie way on
trees that no book on the subject would be warranted unless it
was designed to meet a decided need. At present there is no
general work upon American trees which combines illustrations
of the individual forms with keys for their identification based
upon winter characters. The forester and lumberman, however,
are more called upon to distinguish trees in winter when leaves
and flowers are fallen than in summer. ‘Trees, as the most con-
spicuous elements in the winter landscape, must also appeal to the
student of out door life. The interest shown by classes of school
teachers in the Summer School in identifying specimens of twigs
collected the previous winter indicated that the winter study of
trees can be taken up with enthusiasm by teachers in their schools.
In our experience, the winter identification of trees has proven to
students one of the most interesting subjects of their course. It is
of decided value for its training in the power of accurate obser-
vation. The work comes at a time when material for natural
history study seems scanty and might therefore be used to bridge
over the period between fall and spring which are unfortunately
considered by many the only seasons when study of out door life
is possible in the schools. A tree in winter is far from being
the characterless object many believe. Freed from its covering
of leaves, the skeleton of the tree is revealed and with the method
of branching thus clearly discernible, the species may generally
be more readily identified at a distance than in its summer garb.
There are many forms, moreover, that are difficult to distinguish
from suminer features alone but which in winter have twig, bud
or other characters which make their separation comparatively
easy. It is believed that the combination of keys, text, and illus-
trations from photographs will furnish the assistance which the
current texts fail to supply and render the identification of our
common trees in winter a relatively simple task.
The text with keys is an outgrowth of outlines that one of the
authors has developed and used with various modifications for
the last four years in his college classes in Botany and Forestry.

NEW ENGLAND TREES IN WINTER.
The photographie illustrations are all originals, most of them
by the other author. Although one of us is responsible for the
text and for the selection of the material photographed and the
other for the photographs, we have freely consulted and the
bulletin is therefore to be considered a joint publication.
The order of arrangement of the species in the text and the
scientific names follow the-usage of the seventh edition of Gray’s
Manual and the latter are in aecord with the rules laid down in
the Vienna Congress. The figures and descriptions given are of
trees for the most part growing wild in New England. A few
rarer species which occur in New England only very locally or in
isolated instances have been omitted from illustration. In their
places, however, some of the more frequently cultivated trees, have
been included because of their value for forestry planting in New
England or beeause of their familiarity in city ornamental plant-
ings. The varieties of cultivated forms are so numerous that it is
obviously possible to take account of only the most common types.
Their inclusion, it is believed, will add to the value of the publi-
cation especially for its use in cities. The keys can be absolutely
relied upon only for the species just mentioned from New England.
New England, including as it does the meeting ground between
the northern and southern floras, is extremely rich in the species
of trees represented. The bulletin, therefore, especially in its
descriptive text and illustrations should prove of service outside of
the geographically restricted region described.
The final keys to the genera and to the species as well as the
descriptive text in galley were placed in the hands of the present
s in Botany and Forestry. A student after finding
year’s cla
the species by the keys, read the twig characters in the galley
and signed his name opposite the species if the description corres-
ponded with the twigs supplied. All of the trees described and
illustrated have thus been checked up hy students and some of them
by as many as seventy different persons. In this way limitations
to the use of certain of the characters employed as means of
separating allied species have been discovered and the constancy
of other characters has been confirmed in so far as the material
available could allow. The greatest assistance rendered by the
students, however, has heen in disclosing difficulties in the use of
the keys, due to unfortunate choice of contrasted characters or of
STORRS AGRICULTURAL EXPERIMENT STATION. 309
terms used in their description. The keys in conse-
quence have been considerably modified before final paging.
Many of the explanatory phrases which may appear to
be unnecessary have been inserted at the demand of the students.
Where possible the most obvious characters have been employed
and though the keys in consequence have become somewhat more
cumbersome it is hoped they will prove more usable. Errors
and omissions have no doubt crept in despite the efforts to avoid
them. We would be grateful for any additions or corrections that
may be suggested in the descriptions or keys in view of a possible
revision of the text.
The photographs of the twigs and of the fruit of the deciduous
trees are very nearly natural size. They have been slightly reduced
in production but all of them to the same scale, except the
fruits of the Catalpa, the Chestnut, and the Honey Locust as
indicated under these species. Line drawings or touched-
up photographs would no doubt show important details
more clearly by emphasizing certain of the minute markings.
Since, however, these details are often obscure, and moreover receive
full recognition in the accompanying text, it has been thought that
a truer idea of the twigs would be gained if they were left as they
appeared in the photographs. Accordingly, they have not been
“doctored” in preparation or reproduction. The leafy twigs of the
cone-hearing evergreens have been more or less reduced as indicated
under the descriptions of the genera in the key. All the twigs
of a single genus, however, are on the saine scale.
LITERATURE
The following is a list of books which will be found useful
to the student of New England trees. They have been freely
consulted, as well as others not listed, and have been of value
in determining the ranges and wood characteristics of the indi-
vidual species, in confirmation of bark and habit characters, and
to a less degree of the other winter features. The dimensions of
the trees in the heading “Habit” and the information under the
heading “Distribution” have been taken with little change from
Dame & Brooks’ Handbook, except what is given in the subhead-
ing “In Connecticut” which was obtained from the catalog of
the flowering plants and ferns of Connecticut; Bulletin No. 14,
310 NEW ENGLAND TREES IN WINTER.
Conn. Geol. and Nat. Hist. Survey, 1910. The characters under
the heading “Wood” were taken chiefly from Sargent’s Manual.
To obtain information in regard to the dimensions, the distribution
and the wood characters of cultivated species, Bailey’s Cyclopedia
of Horticulture and various European works have been freely
consulted.
GENERAL Works ON TREES.

INTRODUCTION
Before considering the individual trees in detail it seems de-
sirable to give a general discussion of the different terms used as
headings in the description of the species.
NAME
tree and this name is used throughout the book as the designation
A common English name heads the description of each
of a particular species. The same form may be known
in. different localities by several entirely different common
names. Thus the Tupelo in some places is called only Pepperidge,
in others, Sour Gum or Black Gum. After consultation with the
literature the name Tupelo was chosen as being somewhat more
desirable for the whole of New England than the other names
given in smaller type as synonyms. Often several common names
may be in about equally frequent use. There is, however, only
one scientific name at present sanctioned by botanical authorities
and this is placed first, followed by the Latin synonyms in italics.
HABIT—By the word habit, we denote the general appearance
of a tree seen as a whole. A tree strictly speaking is generally
considered as a woody growth having an undivided trunk at the
base and rising to at least twice the height of a man. cosa en om aL ga eve cate coe hoa a estan ean oe cael fs CORN A Plum (Prunus) 4)

PWS (MO Wye re slender than those of White Ash, densely velvety-
downy in typical condition but often without down especially in the
Green Ash [Fravinus pennsylvanica, var. lanceolata (Bork.) Sarg.].
LEAF-SCARS—Semicircular, upper margin rarely somewhat de-
pressed.
BUDS—Dark rusty brown smaller and narrower than those of the
White Ash, about 2 pairs of scales visible to terminal bud.
FRUIT—Seed-bearing portion round in section, marginless below with
wing extending down its sides.
COMPARISONS—The Red Ash is not distinguished by most people
from the White A which it closely resembles. The downiness of its
twigs which is considered its chief specific character is not constant.
The shape of its leaf-scar, in general semi-circular with upper margin
not concave, is perhaps its best distinguishing character. I‘urther its
terminal buds are narrower, showing fewer scales and the twigs are
more slender. The smooth-twigged Green Ash [Frazinus pennsylvanica,
var. lanceolata (Bork.) Sarg.] is considered by the st authorities only
a variety of the Red. The Black Ash is best separated by its char-
acteristic scaly bark and generally black buds.
pa
The European Ash [Frazrinus excelsior L.] is frequently cultivated. It
has a bark resembling that of the White Ash and has a pair of lateral
buds nearly on level with terminal buds; but its leaf-scars are semi-
eircular and its buds jet black.
DISTRIBUTION—River banks, swampy lowlands, margins of streams
and ponds. New Brunswick to Manitoba; south to Florida and Alabama;
west to Dakota, Nebraska, Ikansas, and Missouri.
IN NEW ENGLAND—Maine—infrequent; New Hampshire—occasional,
extending as far north as Boscawen in the Merrimac valley; Vermont—
common along Lake Champlain and its tributaries; occasional in other
sections; Massachusetts and Rhode Island—sparingly scattered through-
out.
IN CONNECTICUT.
Frequent.
WooD—Heavy, hard, rather strong, brittle, coarse-grained, light
brown with thick lighter brown sapwood streaked with yellow; some-
times confounded commercially with the more valuable wood of the
White Ash.

BLACK ASH
Hoop, Swamp, Basket or Brown Ash.
Fraxinus nigra Marsh.
F. sambucifolia Lam.
HABIT—A tall tree 60-80 ft. in height with trunk diameter of 1-2 ft.,
larger further south; in swamps in company with other trees with tall
slender trunk of nearly uniform diameter to point of branching sup-
porting a narrow head; in the open, where it is seldom found, said to
have a habit similar to that of the White Ash
BARK—Ash-gray, slightly tinged with buff, without deep ridges,
forming thin scales smoothish on the outside and edges, easily rubbed
off and exposing a surface rather soft to the touch suggesting some-
what the feel of asbestos or talcum powder; trunk frequently with
knobby excrescences,
TW1GS—Very stout, similar to those of White Ash but lighter gray
and not shiny.
LEAF-SCARS—Opposite, large, conspicuous, circular to semi-circular;
the upper margin not concave, often extending upward as a thin flap
partially hiding the bud; otherwise resembling the White Ash.
BUDS—Resembling those of White Ash but generally decidedly black
though occasionally rusty, terminal bud ovate, pointed, as long as or
longer than broad, more or less flattened at rig&t angles to outer pair of
scales, last pair of lateral buds generally at some distance from the
end giving terminal bud a stalked appearance. BUD-SCALES—of
terminal bud broadly keeled and narrower than in White Ash, generally
only 1-2 pairs visible.
FRUIT—With broad wing, distinctly notched at apex, surrounding
the flattened seed-bearing portion.
COMPARISONS—The Black Ash is easily distinguished from the
White by its soft, scaly bark, the even or raised upper margin of its
leaf-scars, its narrower and generally black buds, and the stalked ap-
pearance of its terminal bud. When growing in the swamps beside the
White Ash its twigs can be seen to be much stouter and fewer than
those of the latter species.
DISTRIBUTION—Wet woods, river bottoms, and swamps. Anticosti
LEP OREn ESTED south to Delaware and Virginia; west to Arkansas and
Missouri.
IN NEW ENGLAND—Maine—common; New Hampshire—south of the
White Mountains; Vermont—common; Massachusetts—more common in
central and western sections; Rhode Island—infrequent.
IN CONNECTICUT—Occasional,
WwooD—Heavy, rather soft, not strong, tough, coarse-grained, durable,
easily separable into thin layers, dark brown with thin light brown
often nearly white sapwood; largely used for the interior finish of
houses and cabinet-making, and for fences, barrel hoops and in the
manufacture of baskets.

HARDY CATALPA
Cigar Tree, Indian Bean, Western Catalpa.
Catalpa speciosa Warder.
HABIT—A tall tree reaching 100 ft. in height and 4 ft. in trunk
diamenter in the Ohio basin, of smaller dimensions in New England
with slender branches, forming a comparatively narrow round-topped
head.
BARK—Reddish to grayish brown, with longitudinal scaly ridges.
TW1GS—Stout, smooth or slightly short-downy, reddish to yellowish-
brown, the tips of twigs generally winter killed). LENTICELS—
conspicuous, rather large and numerous. PITH—white, wide, occasion-
ally chambered at the nodes.
LEAF-SCARS—Opposite or more frequently 3 at a node, large
and conspicuous, round to elliptical, with depressed center. STIPULE-
SCARS—absent. BUNDLE-SCARS—conspicuous, often raised, forming a
closed ring.
BUDS—Terminal bud absent, lateral buds small, semi-spherical,
generally under 2 mm. high. BUD-SCALES—brown, loosely overlapping,
about 5 or 6 visible.
FRUIT—A long cylindrical capsule, 8-20 inches in length, with nu-
merous flattened, winged, white-hai fringed seeds, persistent on
the tree through winter. The photograph of the capsule is reduced to
about 35 natural size.
COMPARISONS—The 8 large circular leaf-scars at a node with
complete ring of bundle-scars renders the Catalpa twig easily recog-
nizab e. The long cigar-like fruits that hang on the tree supply a
distinctive habit character. A very closely related southern and less
hardy species the Common Catalpa [Catalpa bignonioides Walt.] was
formerly more planted than the Hardy Catalpa. It is a smaller tree
with a rather more spreading habit but is most readily distinguished
from the western species at the time of flowering.
DISTRIBUTION—Not native in New England but planted as an orna-
mental shade tree and for timber. It grows native along borders of
streams and ponds and rich often inundated bottom-land; southern
Indiana, Illinois, and Missouri south into Kentucky, Tennessee and
Arkansas. 7
